Disaster Recovery?

[John Blakley]

All,

I have a situation that we're trying to figure out. What's been requested is that we have a way of mirroring our VM servers from our corporate site to the DR site. They want to keep the same subnets that we have at corporate, and be able to use these at the DR site.

I've thought about L2TPv3, but that's not going to help with the subnets (your thoughts?). I believe this is going to be impossible to do. How do you handle remote site DR?

I know this is an old thread but I figured I would throw in my 2 cents...

We are trying to do the exact same thing and are looking into the Conditional Advertisement Feature of BGP.

if you use conditional advertisement, how can you maintain Single IP for Customer Access across DC and DR ?
